Tentative Explanation

ABSTRACT Radiologically thyroidectomized female Swiss mice were injected intraperitoneally with 131I-labeled thyroxine (T4*), and were studied at time intervals of 30 minutes and 4, 28, 48 and 72 hours after injection, 10 mice for each time interval. The organs of the central nervous system and the pituitary glands were chromatographed, and likewise serum from the same animal. The chromatographic studies revealed a compound with the same mobility as 131I-labeled triiodothyronine in the organs of the CNS and in the pituitary gland, but this compound was not present in the serum. In most of the chromatographic studies, the peaks for I, T4 and T3 coincided with those for the standards. In several instances, however, such an exact coincidence was lacking. A tentative explanation for the presence of T3* in the pituitary gland following the injection of T4* is a deiodinating system in the pituitary gland or else the capacity of the pituitary gland to concentrate T3* formed in other organs. The presence of T3* is apparently a characteristic of most of the CNS (brain, midbrain, medulla and spinal cord); but in the case of the optic nerve, the compound is not present under the conditions of this study.

Tentative Explanation

The toxicities of sprays of some insecticides used against locusts have been determined. The LD50's of γ BHC, diazinon, and dieldrin to both flying and settled adults of Schistocerca gregaria (Forsk.) were between 0·9 and 1·5 times those of the same formulations when applied as a single drop to the abdomen. The toxicity of these insecticides was not affected by the size of the spray droplets when these ranged from about 60 to 250 µ in diameter. The toxicity of DNC, however, was always less by spray application than when applied by micro-drop syringe and was affected by the droplet diameter (droplets of 100 µ being 1·5 times as toxic as those of 200–230 µ) and by whether the locusts were sprayed in flight or when tethered on a card (those in flight being about 1·6 times as susceptible to 100 µ droplets as those at rest). A tentative explanation of this effect is given.The speed of action of the insecticides was compared and the effects of flight activity on susceptibility to the insecticides when sprayed over the flying insects was examined, but none could be detected by the technique used.

Tentative Explanation

Sexually selected characters may reveal information about individual quality during mate choice. Fin display and sound emitted with the aid of specific drumming muscles are characters described as being of importance in the reproductive behaviour of cod (Gadus morhua L.). We examined whether the mass of drumming muscles or fin size was sexually dimorphic, and whether these characters could provide information about male cod that was potentially of benefit to mate-seeking females. The mass of drumming muscles, but not fin size, was sexually dimorphic, with males having larger muscles than females. Neither the mass of drumming muscles nor fin size apparently revealed information about traits that may be associated with parasite resistance in males (i.e., parasite intensities and leukocyte densities). However, variation in fertilization potential (i.e., spermatocrit level) among males was related to both mass of drumming muscles and fin size. Thus, by evaluating sound and fin size, mate-seeking females may obtain information about fertilization ability among males. This may be of particular importance for females in a species whose eggs commonly remain unfertilized. Furthermore, males with large drumming muscles and small fins had low spermatocrit levels. This may reflect reductions in sperm density resulting from frequent ejaculations by attractive males. A costly allocation of resources for the development of drumming muscles at the expense of fin muscles used for propulsion is presented as a tentative explanation as to why females should pay attention to these particular traits during courtship. Increased investment in "song" may thus appear at the expense of "dance."

Conflict Research

Proxy wars are still under-represented in conflict research and a key cause for this is the lack of conceptual and terminological care. This article seeks to demonstrate that minimising terminological diffusion increases overall analytical stability by maximising conceptual rigour. The argument opens with a discussion on the terminological ambivalence resulting from the haphazard employment of labels referencing the parties involved in proxy wars. Here, the article introduces an analytical framework with a two-fold aim: to reduce label heterogeneity, and to argue in favour of understanding proxy war dynamics as overlapping dyads between a Beneficiary, a Proxy, and a Target. This is then applied to the issues of defining and theorising party dynamics in proxy wars. It does so by providing a structural-relational analysis of the interactions between the above-mentioned parties based on strategic interaction. It presents a tentative explanation of the proxy relationship by correlating the Beneficiary’s goal towards the Target with the Proxy’s preference for the Beneficiary. In adding the goal-preference relational heuristic, the article advances the recent focus on strategic interaction with a novel variant to explanations based on interest, power, cost–benefit considerations or ideology.

Crystalline Electric Fields

We discuss the origin of the crystalline electric fields for rare earth ions in transition and noble metal hosts, in terms of the band character of the host material and of localization and delocalization of 5d electrons on the rare earth ions. A tentative explanation is given for the almost pure negative point charge character found in Pd and Pt.
